STYLIFER. 225 



(Clark) ; and Burrow Island (S. H.), have likewise fur- 

 nished it to collectors. 



STYLIFER. Broderip. 



Shell subglobose or conical, smooth and polished, niany- 

 whorled, the apex produced and styliform. Mouth sub- 

 ovate, acuminated above, rounded below ; pillar-lip curved, 

 smooth. No opercidum. 



Animal with slender, cylindrical tentacula, the eyes 

 small and immersed at their external bases. Mantle (ac- 

 cording to Broderip) thick, fleshy, reflected on the last 

 whorls of the shell ; foot ample, long, linguiform, produced 

 and provided with a conspicuous raentum in front ; tongue 

 unarmed. A single branchial plume. 



We are indebted for the first account of this most curious 

 animal to a highly accomplished British naturalist, who 

 has done much good service to malacology. The anoma- 

 lous shell termed Phasianella stylifera by Turton, was the 

 first species discovered ; it was placed in Velutina by Dr. 

 Fleming, who, however, predicted its probable generic im- 

 portance, and suggested the name Styllna. Among the 

 discoveries of the indefatigable Hugh Cuming, were several 

 species congeneric with the British shell, and like it para- 

 sitic on Echinoderms. The animal of one of these was 

 fortunately preserved. Since then the creature has been 

 observed and delineated when alive by Mr. Arthur Adams, 

 a gentleman whose researches during the later voyages 

 of Sir Edward Belcher have given him a worthy place 

 among British naturalists, and on our own shores by Mr. 

 Alder. 



M. Alcide d'Orbigny in his " Paleontologie Fran9aise," 

 has suggested the union of Stylifer with Eulima, and has
